General Characterization
Desmodur BL 3575/1 MPA/SN is a blocked aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI).
It is suitable for use in combination with Desmophen® grades to formulate lightfast, one-component stoving polyurethane coatings.
It is suitable for use in combination with Desmophen® grades to formulate lightfast, one-component stoving polyurethane coatings.
Storage Conditions
Desmodur BL 3575/1 MPA/SN should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product. Recommended storage temperature is 0º-30ºC.
